The present invention provides a water-resistant composition for adsorbing volatile organic compounds (VOCs) derived from organic matter comprising: a) palladium doped hydrogen-ZSM-5, wherein the Si:AI ratio of the hydrogen-ZSM-5 is less than or equal to 200:1; and b) at least one water-soluble binder. The invention also provides the use of the water-resistant composition for adsorbing volatile organic compounds (VOCs) derived from organic matter. La présente invention concerne une composition résistant à l'eau utilisée pour adsorber des composés organiques volatils (COV) issus de matière organique comprenant :a) de l'hydrogène-ZSM -5 dopé au palladium, avec un rapport Si : Al de l'hydrogène-ZSM -5 qui est inférieur ou égal à 200 : 1; et b) au moins un liant soluble dans l'eau. L'invention concerne également l'utilisation de la composition résistant à l'eau pour adsorber des composés organiques volatils (COV) issus de matière organique.
